Fuel Gas Container

ABSTRACT

A fuel gas container includes a body defining an open end and from which a cavity extends with respect to the body longitudinally. The fuel gas container also includes filling adapted to be filled into the cavity. The filling can absorb and mix with liquefied fuel gas and turn the liquefied fuel gas into pulpy or semi-fluid form. Accordingly, the semi-fluid fuel gas can quickly vaporize into gasified fuel gas. Furthermore, a lid which closes the open end of the body after the filling is disposed in the cavity is provided.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fuel gas container, in particular, tosuch a container that is adapted for transforming liquefied fuel gasinto gasified fuel gas.

2. Description of the Related Art

A blowtorch, or a welding torch, or a lighter or other lightingapparatus may either has a chamber to thereby allowing fuel gas to befilled into or an adapting device for connecting with a bottled fuel gasin order to be supplied with fuel gas. The fuel gas is generally storedin liquefied state and the liquefied fuel gas should be converted intogaseous state when using these lighting apparatuses. One reason for thisis that air can effectively mix with the gasified fuel gas and allow thefuel gas to be burned efficiently. Another reason is that burningliquefied fuel gas is dangerous, as the tongues of fire produced is notstable and difficult to be controlled. However, a problem which is oftenencountered is that the liquefied fuel gas is still fed to the lightingapparatus during its use. It is therefore especially beneficial if onlygasified fuel gas can be supplied.

Referring to Taiwan Patent No. 329291, a polyvinyl alcohol is used as asponge to absorb liquefied fuel gas stored in the chamber or bottle.However, the polyvinyl alcohol (PVA) suffers several problems. Oneproblem is that the fuel gas absorbed by polyvinyl alcohol is still inliquefied state. Another problem is that PVA has limited deformabilityand is susceptible to abrasion.

The present invention is, therefore, intended to obviate or at leastalleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

A fuel gas container includes a body defining an open end and from whicha cavity extends with respect to the body longitudinally. The fuel gascontainer also includes filling adapted to be filled into the cavity.The filling can absorb and mix with liquefied fuel gas and turn theliquefied fuel gas into pulpy or semi-fluid form. Accordingly, thesemi-fluid fuel gas can quickly vaporize into gasified fuel gas.Furthermore, a lid which closes the open end of the body after thefilling is disposed in the cavity is provided.

It is an objective of this invention to provide filling that can makeliquefied fuel gas become pulpy or semi-fluid and the semi-fluid fuelgas can quickly vaporize into gasified fuel gas.

It is another objection of the present invention to provide the filling2 which can be used repeatedly for mixing with liquefied fuel gas.

Other objectives, advantages, and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 through 3, a fuel gas container 1 includes a body10 defining an open end 11 and from which a cavity 12 extends inwardwith respect to the longitudinal axis of the body 10. The fuel gascontainer also includes filling 2 adapted to be filled into the cavity12. The filling 2 is filled into the cavity 12 at the open end 11 of thebody 10. The filling 2 is super absorbent polymer and is adapted toabsorb and mix with liquefied fuel gas in order to make the liquefiedfuel gas become pulpy or semi-fluid. By mixing the liquefied fuel gaswith the filling, the semi-fluid filet gas can quickly vaporize intogasified fuel gas and can be prevented from being drawn. Moreover, thefilling 2 is not consumable and therefore can be used repeatedly formixing with the liquefied fuel gas. Moreover, the filling 2 has 100times better absorbing rate than polyvinyl alcohol (PVA).

The fuel gas container 1 also includes a lid 20 for closing the open end11 of the body 10. The lid 20 includes a passage way 21 and a neck 22 bywhich the lid 20 is securely fitted with the body 10.

Referring to FIG. 2 in conjunction with FIG. 4, the fuel gas container 1has a gas transferring means 30 disposed therein for fluidiccommunication with the passage way 21. The gas transferring means 30 iscomprised of a ring 31, a pushing element 32, an elastic element 33 anda siphon tube 34. The fuel gas container 1 also has a gas-receivingmeans 40 formed therein for receiving supply of liquefied fuel gas froma bottled fuel gas 3. The gas-receiving means 40 is comprised of a valve40, an elastic element 42 and a joint 43. In this preferred embodiment,the siphon tube 34 is inserted through the open end 11 of the body 10and includes a first end connected to the joint 43, with a flow path 431defined by the joint 43 being in fluidic communication with the siphontube 34. The elastic element 33 is receivable by the pushing element 32.The siphon tube 34 also includes a second end against which the elasticelement 33 and the pushing element 32 abut. The ring 31 is disposed onthe pushing element 32 and is abutted by the lid 20. Furthermore, thevalve 41 includes a flow passage 411 adapted to allow liquefied fuel gasto flow past and an orifice 412 adapted to allow the liquefied fuel gasto flow into the joint 43. In addition, the joint 43 has a bore 432 thatallows the liquefied fuel gas to flow into the cavity 12 such that thefilling 2 is mixed with the liquefied fuel gas. Accordingly, theliquefied fuel gas is turned into a pulpy or semi-fluid form and isadapted to quickly vaporize into gasified fuel gas.

A second embodiment of the present invention is shown in FIG. 6, whereinlike numerals are employed to denote like components of the firstembodiment. The second embodiment is similar to the first embodimentexcept that super absorbent polymer (SAP) powder is replaced by powderedrecycled paper.

FIGS. 7 through 9 show a third embodiment of a fuel gas container 1embodying the present invention. The fuel gas container 1 includes abody 10′ defining an open end 11′ and from which a cavity 12′ extendsinward with respect to the longitudinal axis 10′ of the body 10′. Thecavity 12′ has the filling 2 disposed inside. The filling 2 is filledinto the cavity 12′ at the open end 11′. A lid 20′ is secured to thebody 10′ for closing the open end 11′. The lid 20′ includes a controlvalve 21′ for dispensing the gasified fuel gas inside the body 10′ and ahole 22′ through which the gasified fuel gas in the body 10′ can flowinto the control valve 21′.

A fourth embodiment of the present invention is shown in FIG. 10,wherein like numerals are employed to denote like components of thethird embodiment. The fourth embodiment is similar to the thirdembodiment except that super absorbent polymer (SAP) powder is replacedby powdered recycled paper.

Accordingly, it is an advantage of the present invention that thefilling 2 is provided. The filling 2 can make the liquefied fuel gasbecome pulpy or semi-fluid and the semi-fluid fuel gas can quicklyvaporize into gasified fuel gas. Thus, the fuel gas container inaccordance with the present invention is adapted to supply gasified fuelgas.

Another advantage of the present invention is that the filling 2 whichcan be used repeatedly for mixing with liquefied fuel gas is provided.
